/**
 * Buffers the source Observable values until the size hits the maximum
 * `bufferSize` given.
 *
 * <span class="informal">Collects values from the past as an array, and emits
 * that array only when its size reaches `bufferSize`.</span>
 *
 * ![](bufferCount.png)
 *
 * Buffers a number of values from the source Observable by `bufferSize` then
 * emits the buffer and clears it, and starts a new buffer each
 * `startBufferEvery` values. If `startBufferEvery` is not provided or is
 * `null`, then new buffers are started immediately at the start of the source
 * and when each buffer closes and is emitted.
 *
 * ## Examples
 *
 * Emit the last two click events as an array
 *
 * ```ts
 * import { fromEvent } from 'rxjs';
 * import { bufferCount } from 'rxjs/operators';
 *
 * const clicks = fromEvent(document, 'click');
 * const buffered = clicks.pipe(bufferCount(2));
 * buffered.subscribe(x => console.log(x));
 * ```
 *
 * On every click, emit the last two click events as an array
 *
 * ```ts
 * import { fromEvent } from 'rxjs';
 * import { bufferCount } from 'rxjs/operators';
 *
 * const clicks = fromEvent(document, 'click');
 * const buffered = clicks.pipe(bufferCount(2, 1));
 * buffered.subscribe(x => console.log(x));
 * ```

 * @see {@link bufferTime}
 * @see {@link bufferToggle}
 * @see {@link bufferWhen}
 * @see {@link pairwise}
 * @see {@link windowCount}
 *
 * @param {number} bufferSize The maximum size of the buffer emitted.
 * @param {number} [startBufferEvery] Interval at which to start a new buffer.
 * For example if `startBufferEvery` is `2`, then a new buffer will be started
 * on every other value from the source. A new buffer is started at the
 * beginning of the source by default.
 * @return {Observable<T[]>} An Observable of arrays of buffered values.
 * @method bufferCount
